How do I help my adopted child feel secure when they ask about their birth family?

This question comes from love, and that matters. Your child's curiosity isn't a threat to your bond—it's part of knowing themselves. I'd suggest creating space where their questions don't feel dangerous. You might say something like, 'I'm glad you're asking. I don't know everything, but let's figure this out together.' Be honest about what you don't know. If they're old enough, help them understand their story without making it about loss or gain—just truth. The security they need isn't found in pretending their past doesn't exist. It's found in a parent who stays present while they explore it. Your willingness to hold both their love for you and their questions about their origins? That's the belonging they're actually seeking. It won't weaken what you have. It deepens it.
